DIAGNOSIS
REPAIR PROCEDURE B – ODYSSEY
If the headlights dim when the engine is running,
connect the HDS to the DLC:
1. Replace the under-hood fuse/relay box:
• Refer to page 22-85 of the 2005–06 Odyssey
Service Manual, or
1. With the HDS in the PGM-FI Data List, start the
engine, and let it idle.
2. Turn on the headlights.
3. Monitor the ELD value on the Data List.
• If the ELD value is less than 18 amps:

• If the ELD value is greater than 18 amps,
disregard this bulletin, and continue with normal
troubleshooting.
NOTE: A faulty ELD may cause the charging
system to fluctuate between 12.5-volt and 14.5-volt
modes with the engine running and the headlights
on. This fluctuation causes the headlights to dim.
Under normal operating conditions, the charging
system operates in the 14.5-volt mode.

select Under-hood Fuse/Relay Box Removal
and Installation from the list.
2. If necessary, clear the DTC with the HDS.
